Generously season pork loin strips with Hog Tale Rub or other good quality pork spice blend. Let sit at room temperature for 1-hour. While the pork is marinating, slice the bell peppers, and quarter the onions. Place the peppers and the onions into a large bowl and toss with olive oil until evenly coated.
In a grill pan or basket, first place the pork loin and top with the pepper-onion mixture. Sprinkle a generous amount of pork seasoning.
Heat grill to high and places basket or grill pan to cook on direct heat for 12-15 minutes. Using tongs toss the mixture frequently until the vegetables are lightly roasted and the pork is no longer pink. Remove the grill basket or pan from the heat. Set aside.
Place the flour tortillas directly on the grill grates for approximately 10 seconds on each side.
To serve, place the pork, pepper and onion mixture, cheese, salsa, sour cream and cilantro into the warm tortilla and fold over.
